Hey guys.. i've got a new mba 2011 etc. i updated lion + safari here a couple of weeks ago and ever since then i havnt been able to log onto my schools wifi. At home, it automaitcally logs on my wifi, and it just works. at my school, it usually logs on to the wifi automatically, and then whenever data is being transfered one way or the other, the browser opens up and i have to use my login i have been provided from the school. Now however it just wont load up that login page, so its basically like being offline. Other people in my class can log on np. They're all using windows PCs though I've tried installing chrome browser to see if that helped, but no. it wont load the page still. It worked fine up untill i installed the lion 1.7.2 update (that also updated safari) - thats why i'm asking here and not on my schools retarded IT department what can i do?
